setup.py + README tidying (#22)

* Convert `README.md` to `README.rst` since rst is all that PyPI supports
* Tidy up README so all functions are explained with their own headers
* Use context managers for opening files in `setup.py`
* Don't import the code in `setup.py`, which doesn't work on some platforms before it's installed. Instead use parsing of the file to find the version.
